Shantel offers online tutorial services. She charges $25.00 an hour per student. Her budget tracker reflects a total of $3,200.00 monthly expenses. How many hours must Shantel work each month to earn a monthly profit of at least $600.00?

1 answer

Let's denote the number of hours Shantel must work each month as x.

Her earnings from tutoring each month can be calculated as 25x, as she charges $25.00 per hour per student.

Her total expenses each month are given as $3,200.00.

Her profit each month can be calculated as her earnings minus her expenses, so it is given by the equation:
Profit = Earnings - Expenses
Profit = 25x - 3,200.00

We are given that Shantel wants to earn a monthly profit of at least $600.00, so we can set up the inequality:
Profit ≥ 600.00
25x - 3,200.00 ≥ 600.00

To solve for x, we can first add 3,200.00 to both sides of the inequality:
25x - 3,200.00 + 3,200.00 ≥ 600.00 + 3,200.00
25x ≥ 3,800.00

Finally, we can divide both sides of the inequality by 25 to solve for x:
(25x)/25 ≥ 3,800.00/25
x ≥ 152.00

Therefore, Shantel must work at least 152 hours each month in order to earn a monthly profit of at least $600.00.
